To all whom it may concern: 1

Be it known that I, BENJAMIN D. KEN- NEY, a citizen of the United Statesof Amerpurpose.

In the accompanying drawing showing it ica, residing at East Liverpool,in the county of Columblana and State of Ohio, have invented a certainnew and useful Improvement in Mantle-Ring Moldsyof which the followingis a specification.

This invention relates to molds and particularly to'mantle ring molds,the object of my invention being to provide a simply operated andefiioient mold} by which theproduction of mantle rings and like objectsmay be more expeditiously effected than with the molds now in common usefor-this mold in which my invention is incorporated, Figure l is a sideelevation-of the mold partly broken ,ggway; Fig. 2 is a sectional planview thelcof; and Fig. 3 is a perspective view of the ring formed by theL 168;

Referring to the drawings, the stationary body A of the mold which issecured in any suitable manner to a supporting frame B, is provided witha circular recess 1 in which is located. a central pedestal 2.Surrounding this, pedestal and working in the space between it and thebody of the mold I provide a ring 3 which serves not only. asthe bottomof the lower die but also as a lifting ring being connected with lostmotion to the pedal operated lifting rod 5. The sides of the lower dieare formed bya. s lit ring, the halves of which are formed at t 1e innerends of the sliding arms 6 passing through slots 7 in the body of themold and conneeted'by a rocking lever or other suitable mechanism 8 withthe lifting rod 5. Springs 16 tend to keep the arms 6 together and thespreading action of the rocking lever 8 is opposed by the tensionthereof. I I

The up er die comprises a forming ring 9 on the face of the plunger 10and recesses 11 which with the inwardly projecting lugs 11 enteringcorresponding slots 12 in the pedestal 2, form the supports 17 of thefinished:ring. Locking pins 13 carried by the upper die enter re steringholes 14 and15 in the arms 6 and ody A respectively so as to firmly lockthe arms and prevent their spreading-under the pressure of the upperdie. I

The operation ofthe mold isas fo1l ows:-

space above they ring 3 tion so-that the ring 3 is ,at the bottom of thelower die and the split ring closed under the actionof thesprin'gs 16,the clay or other substance to be moldedfis thrown'into the and theupper die lowered. Descending, the pins enter the holes 14 and 15 andlock the arms 6 during has been lifted, the lifting rod- 5 is actuated.

6 and then raises the ring 3 until the molded mantle ring is flush withor above the body A of the mold whence it may be readily removed.

It will be readily understood that my im-.

proved mold may be adapted for use in connection with other objects thanmantle rings and that various modifications of my construction may bemade without departing from the scope of my invention.

'1 claim as my invention:

1. In a mold of the character'described, a die having a fixed bodyportion provided with guide slots, spring actuated side members workinin said slots and adapted to form sides of the die during the moldlngoperation, in combination with means to remove the molded article fromthe mold and means in connection therewith to move said side membersagainst the tension of said actuating springs, said side members beingadapted to be withdrawn from the die after the molding is complete andbefore the -molded article is removed.

The lifting rod 5 beingfin its lowermost posi I the period of pressure..After the upper die Its upward movement first spreads the arms plungerdie to lock said side members in position during said molding operationand means to withdraw said side membersfrom the die after the molding iscom lete and before the molded'article is remove 3. In a mdld' of thecharacter described, a I

die having a fixed body portion provided with guide slots, springactuated side members working in said' slots and ada ted to form sides'of the die during the mol lng'operation and a bottom part adapted toserve as a lifting member as well as a base for the mold, in combinationwith means to lift said base and'means in connectiontherewith toWithdraw said side members before the base is actuated.

In a mold of the character described, a die during the moldingoperation, in combiwith gui e slots, side members working in said slotsand adapted to form sides of the die during the molding operation, incombination with means carried by the cooperating die to lock said sidemembers in position during said molding operation and means to Withdrawsaid side members from the die after the molding is complete and beforethe molded article is removed.

5. In a mold of the character described, a die having a fixed bodyportion and spring actuated side members laterally movable twosubscribing witnesses.
